Title: Insoluble anode
Inventor: MANABE MAKOTO
IPC: C25B11/10
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To prevent the formation of a passive form between an electrode base body and an electrode active layer by interposing an adequately controlled diffusion layer between the electrode base body and the electrode active layer. SOLUTION: This insoluble anode A has the electrode base body 10 made of, for example, Ti, the diffusion layer 12 deposited thereon and the electrode active layer 11 made of, for example, Pt, deposited on the diffusion layer 12. As a result, the adequately controlled diffusion layer 12 between the base body 10 and the active layer 11 may be made to develop an electrochemical grading function. Consequently, the formation of the passivated film between the base body 10 and the active layer 11 is prevented and, thereafter, the electrode function may be accomplished until the active layer 11 consumes completely. The active layer 11 is diffusion joined onto the base body 10, by which the adhesion property between both is enhanced and both layers are made hardly peelable.  Since the formation of the base body 10 and the active layer 11 to the higher density is possibly, high continuity with lesser IR loss is assured and, more particularly, this insoluble anode is useful as an oxygen generating abode at a high current density of >=150A/dm<2> .
